Embodiment 1
[0070] The preparation of embodiment 1, red dye monomer (I)
[0071] 6.15 grams of reactive dye reactive brilliant red X-3B (615g / mol), 30 grams of organic solvent tetrahydrofuran and 7.2 grams of double bond functionalization reagent hydroxypropyl methacrylate are added in the there-necked flask, and then 0.8 grams of mass percent concentration is added. 10% aqueous solution of accelerator sodium hydroxide, stirred and mixed and heated up to 60°C, replaced for 8 hours, added 400 ml of water to the flask after completion, filtered after standing, washed the filter cake with water until the filtrate was colorless, collected the filtered Cake, after drying, the red dye monomer (I) was obtained.
[0072] The reaction equation of above-mentioned preparation dye monomer is as follows:
[0073]
Embodiment 2
[0074] The preparation of embodiment 2, red polymer emulsion (I) (method one)
[0075] 1) Prepare gained red dye monomer (I) with 0.4 gram embodiment 1, 1.5 gram cross-linking monomer diacetone acrylamide, 0.3 gram main monomer methacrylic acid, 19 gram main monomer styrene and 19 gram main monomer Bulk butyl acrylate was mixed and stirred to fully dissolve to obtain mixed monomers.
[0076] 2) Dissolve 0.3 g of initiator ammonium persulfate in 10 milliliters of water to obtain an aqueous solution of initiator ammonium persulfate.
[0077] 3) Mix 6 grams of mixed monomers obtained in step 1), 50 milliliters of water, 0.3 grams of emulsifier nonylphenol polyoxyethylene ether (OP-10), 0.6 grams of emulsifier sodium lauryl sulfate and 0.15 grams of buffer carbonic acid Add ammonium hydrogen into the three-necked flask, stir and mix, and when the temperature rises to 70°C, add 4 ml of the aqueous solution of ammonium persulfate obtained in step 2) to the system, start timing from...
